If you see other packages, such as '''perl''' or '''php''', '''abort the installation'''. This might occur because you have installed '''perl-CGI-Session''' or '''perl-DBD-Pg'''.

== How to install Postgres 12 - old method ==
 
−
 
−
This is an old method and the systemd method below should be used
 
−
 
−
{{Note box|This howto is intended for use with SME Server 10, although it may work for other versions.}}
 
−
 
−
Postgres 12 is one of the latest versions available. The directions here may apply to other versions as well. The installation of version 12 uses RPMs directly from the Postgres support site. The links below come from https://yum.postgresql.org/12/redhat/rhel-7-x86_64/repoview/postgresqldbserver12.group.html but you can adjust the 12 in this link to a different version and get a different version's installation.
 
−
 
−
First, it is necessary to install the dependencies as well as the contrib RPM.<syntaxhighlight>
 
−
yum install https://yum.postgresql.org/12/redhat/rhel-7-x86_64/postgresql12-libs-12.5-1PGDG.rhel7.x86_64.rpm
 
−
yum install https://yum.postgresql.org/12/redhat/rhel-7-x86_64/postgresql12-12.5-1PGDG.rhel7.x86_64.rpm
 
−
yum install https://yum.postgresql.org/12/redhat/rhel-7-x86_64/postgresql12-contrib-12.5-1PGDG.rhel7.x86_64.rpm
 
−
</syntaxhighlight>
 
−
 
−
Next, install the server portion.<syntaxhighlight>
 
−
yum install https://yum.postgresql.org/12/redhat/rhel-7-x86_64/postgresql12-server-12.5-1PGDG.rhel7.x86_64.rpm
 
−
</syntaxhighlight>Initialize the database.<syntaxhighlight>
 
−
/usr/pgsql-12/bin/postgresql-12-setup initdb
 
−
</syntaxhighlight>If you have a previously installed version of Postgres, you will need to stop the service for it before starting the service for the new version. Note that the new service name incorporates the version number. It can be started and enabled like this:<syntaxhighlight>
 
−
systemctl start postgresql-12
 
−
systemctl enable postgresql-12
 
−
</syntaxhighlight>
 
−
 
−
 
−
==Koozali SME v10 and systemd==
 
−
 
−
{{Note box| There is now a contrib for Koozali SMEServer v10}}
 
−
 
−
db yum_repositories set postgresql12 repository \
 
−
  BaseURL https://download.postgresql.org/pub/repos/yum/13/redhat/rhel-7Server-\$basearch/ \
 
−
  EnableGroups no \
 
−
  GPGCheck yes \
 
−
  Name "Postgresql-12" \
 
−
  GPGKey https://download.postgresql.org/pub/repos/yum/RPM-GPG-KEY-PGDG-12 \
 
−
  Visible no \
 
−
  status disabled
 
−
 
−
Update yum
 
−
signal-event yum-modify
 
−
 
−
 
−
Install the rpms
 
−
yum --enablerepo=postgresql12 install postgresql12-server postgresql12-contrib
 
−
 
−
Set a config key for SME to recognise the service:
 
−
config set postgresql-12 service status enabled access private
 
−
 
−
We will need a file:
 
−
 
−
mkdir -p /usr/lib/systemd/system/postgresql-12.service.d
 
−
nano /usr/lib/systemd/system/postgresql-12.service.d/50koozali.conf
 
−
 
−
Add something like this:
 
−
 
−
[Unit]
 
−
After=network.target network.service wan.service
 
−
[Install]
 
−
WantedBy=sme-server.target
 
−
 
−
Reconfigure and reboot:
 
−
signal-event post-upgrade;signal-event reboot
 
−
 
−
The service will show as failed at this point.
 
−
systemctl status postgresql-12
 
−
 
−
So we need to init the DB:
 
−
/usr/pgsql-12/bin/postgresql-12-setup initdb
 
−
 
−
Then start it:
 
−
systemctl start postgresql-12
 
−
 
−
And now we can see it running.
 
−
 
−
We can check some of the defaults:
 
−
 
−
grep '^[[:blank:]]*[^[:blank:]#;]' /var/lib/pgsql/12/data/pg_hba.conf
 
−
grep '^[[:blank:]]*[^[:blank:]#;]' /var/lib/pgsql/12/data/postgresql.conf
 
−
